3.4 Tractor Ballast
To ensure tractor stability when operating on flat surfaces the left rear tractor tire MUST exert a minimum
down force (weight) of 1500 lbs. on the ground when the tractor is on level ground, its boom is fully extended
and the mower head is horizontal and two feet above the ground. For units which have the ability to operate
on either side of the tractor, these requirements must also be met for the right side tire when the boom is
extended to the left side as described above. A tractor that does not meet this criteria is DANGEROUS and
should not be operated as upset of the unit can occur resulting in possible serious injury and property
damage. NOTE: All factory mounted units are tested and meet the ballast requirement befor e shipment;
further testing is not required unless the unit is operated in a manner other than what is considered standard
operating conditions.
For additional information on properly ballasting the tractor, refer to Alamo Indu strial Tractor and Mower
Stability Pamphlet P/N #02959010
If the unit is operated on slopes greater than 5°,
a d d i t i o n a l c o u n t e r w e i g h t w i l l b e r e q u i r e d .
Operation of the unit on slopes greater than 11
percent (6.4 degrees) is not recommended under
any circumstances. On a tractor with a 96" outside
to outside tire spread, an 11 percent (6.4 degrees)
slope occurs when one rear tractor tire is about 8"
lower than the other rear tire. OPS-B- 0018
4.GETTING ON AND OFF THE TRACTOR
Before getting onto the tractor, the operator must read and completely understand the implement and tractor
operator manuals. If any part of either manual is not completely understood, consult an authorized dealer for
a complete explanation. OPS-U- 0007
Do not mount or dismount the Tractor while the tractor is moving. Mount
the Tractor only when the Tractor and all moving p arts are completely
stopped.
